what is going on in the HPA axis as a infant and child |
|
Definition
it is very sensitive to estrogen, E2 is <10 and it suppresses the HPA even though its low |

Term
average age of androgenarche |
|
Definition
|
|
Term
what happens in androgenarche |
|
Definition
it is independent of HPA, response to ACTH becomes more sensitive and favors DHEA production |

Definition
|
|
Term
what happens in gonadarche |
|
Definition
the HPA axis becomes less sensitive to estrogen negative feedback and more sensitive to GNRH so FHS/LH are made thus making E2/androgens |
|
|

#1 factor on when someone will go into puberty |
|
Definition
|
|
Term
factors alterning when someone will go into puberty - 4 |
|
Definition
genetics, location, light (differnt in blind people), BMI need 17% |
|
|
Term
why does low BMI alter puberty timing |
|
Definition
leptin is low with low BMI, we dont know why but in puberty leptin is supposed to be high, it is also involved in LH surge, ovulation, and menarche |
|
|
Term
what is the gonadostat theory |
|
Definition
in gonadarche the HPA axis becomes less senesitive to estrogen negative feedback and more sensitive to GNRH |
|

Term
what is a GNRH suppression test |
|
Definition
give lupron 20ug and in 40min test LH, if <6 the the precocious puberty is independent of GNRH, if >6 then it is dependent on GNRH |
